Carbon Charts Vanilla library

The library provides a collection of reusable charting components to build websites and user interfaces. Adopting the library enables developers to use consistent markup, styles, and behavior in prototype and production work.

Install

If using yarn:


$ yarn add @carbon/charts d3

If you prefer npm:


$ npm install --save @carbon/charts d3

Getting started

If consuming through a bundler (e.g. webpack):

index.html
...
<div id="my-bar-chart"></div>
...
index.js
import '@carbon/charts/styles.css';
import { BarChart, defaultColors } from '@carbon/charts';
// grab chart holder DOM element
const chartHolder = document.getElementById('my-bar-chart');
// initialize the chart
new BarChart(chartHolder, {
  data: stackedBarData,
  options: stackedBarOptions,
});

If consuming in a browser environment (e.g. through CDNs):

index.html
<!DOCTYPE html>
<html>
  <head>
    <link rel="stylesheet" href="https://unpkg.com/@carbon/charts/style.css" />
  </head>
  <body>
    <div id="my-bar-chart"></div>
    <script src="https://unpkg.com/@carbon/charts/bundle.js"></script>
    <script>
      // grab chart holder DOM element
      const chartHolder = document.getElementById('my-bar-chart');
      const stackedBarData = {
        // ...see next section
      };
      const stackedBarOptions = {
        // ...see next section
      };
      // initialize the chart
      new Charts.BarChart(chartHolder, {
        data: stackedBarData,
        options: stackedBarOptions,
      });
    </script>
  </body>
</html>

Data and options

Data and options follow the same model in all charts, with minor exceptions and differences in specific components.

For instance, in the case of pie and donut charts, you would only provide one data set. In the case of donut charts, you can pass in an additional field called center in your options configuring the donut center.

There are also additional options available depending on the chart type being used, for more examples please see here.

Below are sample data and options that can be used in a stacked bar chart:

import { BarChart, defaultColors } from '@carbon/charts';
// Use the below if you're loading bundles through a CDN
// const { BarChart, defaultColors } = Charts;
const stackedBarData = {
  labels: ['Quantity', 'Leads', 'Sold', 'Restocking', 'Misc'],
  datasets: [
    {
      label: 'Dataset 1',
      backgroundColors: [defaultColors[0]],
      data: [65000, 29123, 35213, 51213, 16932],
    },
    {
      label: 'Dataset 2',
      backgroundColors: [defaultColors[1]],
      data: [32432, 21312, 56456, 21312, 34234],
    },
    {
      label: 'Dataset 3',
      backgroundColors: [defaultColors[2]],
      data: [12312, 23232, 34232, 12312, 34234],
    },
  ],
};
const stackedBarOptions = {
  scales: {
    x: {
      title: '2018 Annual Sales',
    },
    y: {
      title: 'Figures',
      formatter: axisValue => {
        return `${axisValue / 1000}k`;
      },
      stacked: true,
    },
  },
  legendClickable: true,
  containerResizable: true,
};
